Specification of Letters Patent.

Application filed October 25, 1920. Serial No. 419,223.

To all whom it may concern: 7

Be it known that I, GERVAIS BAILLIO, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have inventeda new and useful Improvement in Electrolytic Cells, of which the following is a full, clear and exact description, reference being ha to the acoompanyin drawings, which form apart .of this speci cation.

This invention relates to an improvement in electrolytic cells for the electrolysls of solutions, and is designed to provide an eflicient cell which is cheap of construction, and which can readily be assembled and taken apart.

' The precise nature of my invention wlll be best understood by referenceto the accompanying drawings, which Wlll now be described, it being premised, however, that various changes may be made in the details of construction, without departing from the spirit and scope of my invention as defined in the appended claims. I

Figure 1 of the drawingsis a side elevation, partially in section, of one form of cell constructed in accordance with my in- Fig. 2 is a sectional plan view thereof.

Fig. 3 is a plan view.

Fig. 4 is a vertical section to an enlarged scale.

Fig. 5 is a detail elevat1on,. with parts broken away, of one of the side members, several of the anodes, and portions of. the

.top and bottom of the cell.

Fig. 6 is a perspective View of one of the 4 anode supports.

A cell built in accordance with my invention, such as illustrated in the drawings, comprises side members 2, a U-shaped memher, having a base 3 and flanges 1 at each end thereof, which forms the bottom and ends of the cell, and a top 5.

The above members are molded of concrete or other suitable plastic material and are secured to each other by means of screw clamps 6, there being a sheet 7 of asbestos between each side member and the other members which form gaskets as well as filters and b aflles between the cell chambers.

The bottom forming member 3 is provided wlth a plurality of parallel longitudinal Y-shaped grooves for centering and retaining the anodes 8 in proper relation to the cathodes 9. The anodes 8, whichI preferably form of graphite, are each provided with a porcelain socket or base member 10 at the lower end, which socket members are provided with triangular shaped flanges on their lower faces for engagement with grooves in the bottom, and upwardly extending triangular flanges on the upper faces and at the edges thereof, to form seats for the bodies of the anodes.

These anodes are also each provided with an upwardly extending stem or terminal 11, WlllCh extend through suitable orifices in the top 5.

The cathodes 9 are formed of perforated sheet 1ron with outwardly extendlng flanges 12, whlch form anchoring means for retainmg the cathodes in position on the sides, and are also provided with terminals 13, which extend through the sides 2.

14 and 15 are outlets from the chambers or recesses 16 formed in the inner faces of the sides 2 under the cathodes 9, 18 is an outlet through the top 5 from the anode compartment, and 17 is an inlet opening through the top 5 for the admission of the l 1%id to be treated.

he various cell forming members are formed of concrete or other plastic material. in suitable molds to form the cavities and openings therein, and the cathodes are secured in position in the sides 2 during the. molding, in such a manner that the outer faces thereof are flush with the inner faces of the side members.

The bodies of the anodes 8 are also formed in suitable forms in connection with the previously formed bases and stems to form unitary structures.

In assembling a cell the anodes are placed in position on the bottom or web 3, and the top 5 is then placed in position on the seats on-the ends or'flange members 4.. A sheet of asbestos is then placed on each side of the structure and the sides are then placed in position and secured by the clam s6. The edges of the sheets 7 of asbestos orm pack- Patented July 26, 1921.

ing oetweenthe abutting members, while the central portions form baffles and strainers between the cathodes and anodes.

The flanged porcelain base members form protectors for the lower ends of the anodes as well as centering means for spacing the anodes with relation ,to the cathodes.

' The cell can also be used as a tank cell by merely making a luted joint between the side members and the body forming portion, and permanently securing the parts together.

If it is desired to form a cell of a different shape than that shown in the drawings, such as a circular cell, the sides and bottom forming portions would be shaped accordingly, and secured to each other.

The advantages of my invention result from the provision of an electrolytic cell which can readily be taken apart for cleaning and repairing and which can readily be reassembled again.

Further advantages result from the elimination of joints on the side of the cell by combining the cathode box, cathode sheet and side of cell in a single side member, whereby brine leakage is avoided, and the chance of air leakage into the anode compartment with consequent dilution of the chlorin gas is reduced to a minimum, when the cell is used for the electrolytic treatment of salt solution. The hydrogen gas from the cathode compartment can be readily collected without making any change in the manner of assembling the cell;

The cost of fabrication of the graphite anodeis small as there are no threaded or doweled joints, or any joints in the anode below the surface of the brine. v
